Nerval's Lobster writes "Whatever your actual feelings about football and this weekend's Super Bowl, you have to admire Wolfram Alpha's willingness to crunch any dataset and see what it can find. The self-billed 'computational knowledge engine' has analyzed the historical data for both teams involved in this Sunday's Super Bowl XLVII. Its conclusion? The San Francisco 49ers and Baltimore Ravens are 'annoyingly similar' when it comes to numbers, although some players stand out as potential game changers — if the math plays out right."

djl4570 writes "xkcd's 'What If' series consists of humorous takes on highly implausible but oddly interesting hypothetical physics questions, like how to cook a steak with heat from atmospheric re-entry. The most recent entry dealt with flying a Cessna on other planets and moons in the solar system. Mars: 'The tricky thing is that with so little atmosphere, to get any lift, you have to go fast. You need to approach Mach 1 just to get off the ground, and once you get moving, you have so much inertia that it’s hard to change course—if you turn, your plane rotates, but keeps moving in the original direction.' Venus: 'Unfortunately, X-Plane is not capable of simulating the hellish environment near the surface of Venus. But physics calculations give us an idea of what flight there would be like. The upshot is: Your plane would fly pretty well, except it would be on fire the whole time, and then it would stop flying, and then stop being a plane.' There are also a bunch of illustrations for flightpaths on various moons (crashpaths might be more apt), which drew the attention of physics professor Rhett Allain, who explained the math in further detail and provided more accurate paths."

An anonymous reader writes "Since the 1960s until the present day, missile defense has been a hot topic. Ronald Reagan popularized the concept with his 'Star Wars' multi-billion dollar plan to use lasers and various technologies to destroy incoming Soviet warheads. Today, America has a sizable sea-based system, dubbed AEGIS, that has been deployed to defend against rogue states missiles, both conventional and nuclear. However, there is one thing missile defense can't beat: simple math. 'Think about it — could we someday see a scenario where American forces at sea with a fixed amount of defensive countermeasures face an enemy with large numbers of cruise and ballistic weapons that have the potential to simply overwhelm them? Could a potential adversary fire off older weapons that are not as accurate (PDF), causing a defensive response that exhausts all available missile interceptors so more advanced weapons with better accuracy can deliver the crushing blow? Simply put: does math win?'"

coondoggie writes "Stanford researchers said this week they had used a supercomputer with 1,572,864 compute cores to predict the noise generated by a supersonic jet engine. 'Computational fluid dynamics simulations test all aspects of a supercomputer. The waves propagating throughout the simulation require a carefully orchestrated balance between computation, memory and communication. Supercomputers like Sequoia divvy up the complex math into smaller parts so they can be computed simultaneously. The more cores you have, the faster and more complex the calculations can be. And yet, despite the additional computing horsepower, the difficulty of the calculations only becomes more challenging with more cores. At the one-million-core level, previously innocuous parts of the computer code can suddenly become bottlenecks.'"

chicksdaddy writes "Google cemented its reputation as the squarest company around Monday (pun intended), offering prizes totaling Pi Million Dollars — that's right: $3.14159 million greenbacks — in its third annual Pwnium hacking contest, to be held at the CanSecWest conference on March 7 in Vancouver, British Columbia. Google will pay $110,000 for a browser or system level compromise delivered via a web page to a Chrome user in guest mode or logged in. The company will pay $150,000 for any compromise that delivers 'device persistence' delivered via a web page, the company announced on the chromium blog. 'We believe these larger rewards reflect the additional challenge involved with tackling the security defenses of Chrome OS, compared to traditional operating systems,' wrote Chris Evans of Google's Security Team."

Frequent contributor Bennett Haselton writes "With the announcement of Verizon's "six strikes plan" for movie pirates (which includes reporting users to the RIAA and MPAA), and content companies continuing to sue users en masse for peer-to-peer downloads, I think it's inevitable that we'll see the rise of p2p software that proxifies your downloads through other users. In this model, you would not only download content from other users, but you also use other users' machines as anonymizing proxies for the downloads, which would make it impossible for third parties to identify the source or destination of the file transfer. This would hopefully put an end to the era of movie studios subpoenaing ISPs for the identities of end users and taking those users to court." Read below for the rest of Bennett's thoughts.

ananyo writes "Mathematicians plan to launch a series of free open-access journals that will host their peer-reviewed articles on the preprint server arXiv. The project was publicly revealed in a blog post by Tim Gowers, a Fields Medal winner and mathematician at the University of Cambridge, UK. The initiative, called the Episciences Project, hopes to show that researchers can organize the peer review and publication of their work at minimal cost, without involving commercial publishers. 'It’s a global vision of how the research community should work: we want to offer an alternative to traditional mathematics journals,' says Jean-Pierre Demailly, a mathematician at the University of Grenoble, France, who is a leader in the effort. Backed by funding from the French government, the initiative may launch as early as April, he says."

DavidHumus writes "The much-publicized international rankings of student test scores — PISA — rank the U.S. lower than it ought to be for two reasons: a sampling bias that includes a higher proportion of lower socio-economic classes from the U.S. than are in the general population and a higher proportion of of U.S. students than non-U.S. who are in the lower socio-economic classes. If one were to rank comparable classes between the U.S. and the rest of the world, U.S. scores would rise to 4th from 14th in reading (PDF) and to 10th from 25th in math."

innocent_white_lamb writes "A researcher says that some letters are over valued and some are under-valued in Scrabble, due to recent changes to the lists of allowable words. Z and X are now much easier to play and should be worth less, while U, M and G should be worth more than they are now. Joshua Lewis wrote a program to re-calculate the value of each letter to better reflect the current usage. The co-president of the North American Scrabble Players Association says that he often hears criticism of Scrabble's scoring system, but any change would bring about 'catastrophic outrage'. A spokesman for Mattel says that they have no plans to change the game."

SchrodingerZ writes "The Viktor Rydberg school in Stockholm, Sweden, has announced that they have included Minecraft into the curriculum for their 13-year-old students. The program is not meant to teach children about math or language, but rather as a tool to inspire creativity in the classroom. 'They learn about city planning, environmental issues, getting things done, and even how to plan for the future,' Viktor Rydberg teacher Monica Ekman told English-language newspaper The Local. 'It's not any different from arts or woodcraft,' she added."

zacharye writes "The Sunday evening Wall Street Journal article claiming that Apple had cut its iPhone 5 display orders drastically for the March quarter made quite a splash. The way WSJ wrote its piece seemed to support the original Nikkei claim about Apple cutting its iPhone 5 display orders in half from the originally planned order of 65 million units. This would be a massive adjustment. But Apple uses the same new display type for both iPhone 5 and the latest iPod touch. Neither WSJ nor Nikkei addressed this, however — both seemed to be referring to just iPhone 5 displays. The math just doesn't add up."

New submitter fractalVisionz writes "The White House has officially responded to the petition to secure resources and funding to begin Death Star construction by 2016, as previously discussed on Slashdot. With costs estimated over $850,000,000,000,000,000 (that's $850 quadrillion), and a firm policy stating 'The Administration does not support blowing up planets,' the U.S. government will obviously decline. However, that is not to say we don't already have a Death Star of our own, floating approximately 120 miles above the earth's surface. The response ends with a call to those interested in STEM (Science, Technology, Engineering, and Mathematics) fields of study: 'If you do pursue a career in a science, technology, engineering or math-related field, the Force will be with us! Remember, the Death Star's power to destroy a planet, or even a whole star system, is insignificant next to the power of the Force.'"

eldavojohn writes "I kickstarted a project undertaken by Daniel Shiffman to write a book on what (at the time) seemed to be a very large knowledge space. What resulted is a good book (amazing by CC-BY-NC standards) available in both PDF and HTML versions. In addition to the book he maintains the source code for creating the book and of course the book examples. The Nature of Code starts off swimmingly but remains front heavy with a mere thirty five pages devoted to the final chapter on neural networks. This is an excellent book for Java and Processing developers that want to break into simulation and modeling of well, anything. It probably isn't a must-have title for very seasoned developers (unless you've never done simulation and modeling) but at zero cost why not?" Read below for the rest of eldavojohn's review.

theodp writes "Education officials with Northwest Nazarene University and the J.A. and Kathryn Albertson Foundation say they are arranging to have Khan Academy classes tested in about two dozen public schools next fall in Idaho, where state law now requires high school students to take online courses for two of their 47 graduation credits. 'This is the first time Khan Academy is partnering to tackle the math education of an entire state,' said Khan Academy's Maureen Suhendra. Alas, the Idaho Press-Tribune reports (alas, behind a paywall) that next fall would be too late for film director and producer Davis Guggenheim (Waiting for Superman, An Inconvenient Truth), who will be in Idaho in January filming The Great Teacher Project, a documentary which will highlight positives of education, like the Khan Academy pilot in Idaho. Not to worry. For the film, a few teachers will implement Khan Academy in day-to-day teaching starting in January, before the entire pilot program launches in fall 2013."

Nerval's Lobster writes "Can data-analytics software win a Super Bowl? That's what the Buffalo Bills are betting on: the NFL team will create an analytics department to crunch player data, building on a model already well established in professional baseball and basketball. 'We are going to create and establish a very robust football analytics operation that we layer into our entire operation moving forward,' Buffalo Bills president Russ Brandon recently told The Buffalo News. 'That's something that's very important to me and the future of the franchise.' The increased use of analytics in other sports, he added, led him to make the decision: 'We've seen it in the NBA. We've seen it more in baseball. It's starting to spruce its head a little bit in football, and I feel we're missing the target if we don't invest in that area of our operation, and we will.'"

jomama717 writes "Another chapter in the fascinating life of Srinivasa Ramanujan appears to be complete: 'While on his death bed, the brilliant Indian mathematician Srinivasa Ramanujan cryptically wrote down functions he said came to him in dreams, with a hunch about how they behaved. Now 100 years later, researchers say they've proved he was right. "We've solved the problems from his last mysterious letters. For people who work in this area of math, the problem has been open for 90 years," Emory University mathematician Ken Ono said. Ramanujan, a self-taught mathematician born in a rural village in South India, spent so much time thinking about math that he flunked out of college in India twice, Ono said.'"

An anonymous reader writes "My kid seems incredibly interested in my Android tablet, but I'm not too comfortable with letting her play with my browser. I've been hunting the app store for apps that I could let my kid play around with, but haven't found much. It seems like most apps are targeted for slightly older kids and are trying to teach them words, math or whatnot. Has anyone found any cool apps for approximately 6-month-old children? I'm mostly looking for something that makes funny noises or where you just have to e.g. track moving objects on the screen."

theodp writes "The BBC News' Laura Gray reports on a juggling notation system developed in the 80's called Siteswap (aka Quantum Juggling and Cambridge Notation) and how it has helped jugglers discover and share thousands of new tricks. Frustrated that there was no way to write down juggling moves, mathematician Colin Wright and others helped devised Siteswap, which uses sequences of numbers to encode the number of beats of each throw, which is related to their height and the hand to which the throw is made. 'Siteswap has allowed jugglers to share tricks with each other without having to meet in person or film themselves,' says James Grime, juggling enthusiast and math instructor for Cambridge University. Still unclear on the concept? Spend some time playing around with Paul Klimek's most-excellent Quantum Juggling simulator, and you too can be a Flying Karamazov Brother!"

skade88 writes "Do you remember those large TI-8X line of calculators with a BW display from when you were growing up and learning all about math? Yeah well, you can still get them because TI has yet to update or change their line of TI-8X calculators from their 96x64 display, processors designed in the 1980s with just a few kilobytes of user accessible memory. They still cost in the $100.00 to $150.00 range. That is all about to change now that the TI-8X line of calculators is 22 years old. Their new TI-84+C-Silver edition will come with a 320x240 16-bit color display, 3.5MB of flash ROM, and 21KB of RAM. Ars has a good preview of the device along with speculation on why it took so so so very long for TI to finally bring calculators up to a level of technology that could have been delivered a decade ago."Last month some photos and a few details of the new TI-84+C were leaked.
